The comedian and actor talks to Digital Spy about his part as Perkins in Doctor Who and being on set with Peter Capaldi: “Anyone who’s in Doctor Who always gets asked if they would come back, and I can’t imagine many people, with the possible exception of Christopher Eccleston, who wouldn’t. Of course, if they said to me, ‘Would you like to be in Doctor Who for the rest of your life’, I’d probably sign on for that.”

He revealed his most cherished discussion about his recent role in Doctor Who: “Steven Moffat sent me an email that said, ‘You are now a personal friend of Doctor Who and nothing can change that’. Even saying that sends a tingle down my neck and spinal cord.”
